I've used several different weather extensions and was not a fan of any. Weather Extension by Tim Leland seems to be much better. I really like this extension because 1. it shows the temp on my bookmarks bar so I don't have to open the whole thing. 2. It is beautiful. and 3. because it seems to give me everything I could want in a weather app. It would be nice in the future if the notifications had sound availability. This leads me to my 4th like about this extension. I sent an email to the developer asking about sound. I had my answer the next day.

I have not given 5 stars because I was just upgraded to the Pro version. Once I've played about with that for a bit, I'll re-review . So all in all a good solid extension. Give it try!
